Getting a shopper to buy is the hard, expensive part — the click already happened, the ad already got paid for, the item is already in the cart. AI upsell and cross-sell apps exist to squeeze more revenue out of that same visit: a bundle suggestion on the product page, a "complete the set" nudge in the cart, or a one-click add-on after checkout that doesn't even ask for payment details again. We compared the Shopify apps sellers actually use for this, from a fully free option to a dedicated post-purchase specialist.

1. Wiser AI — best for "frequently bought together" cross-sells
Wiser's AI reads a shopper's on-site behavior alongside your catalog to build Amazon-style bundle widgets — "frequently bought together," product add-ons, a slide-out cart drawer, and post-purchase offers — without you manually pairing every product by hand. The bundle format matters here: showing a combined price and letting a shopper add the whole set in one click is a familiar pattern that converts better than a generic "you might also like" carousel. Try Wiser AI.
Pros: genuinely free for stores under 50 orders/month, AI-generated bundles need little manual setup, widgets cover product page through post-purchase. Cons: pricing scales with order volume once you outgrow the free tier, and some reviewers flag the billing tiers as worth double-checking before you commit.
2. ReConvert (Upsell.com) — best for building your own post-purchase funnel
ReConvert — rebranded to Upsell.com, though the ReConvert name and app listing are still how most sellers find it — lets you build a multi-step post-purchase upsell funnel with a visual, no-code editor: thank-you-page offers, a countdown-timed deal, a follow-up cross-sell, all triggered by what was actually in the order. It's one of the highest-rated apps in the category, and its free plan (up to 49 orders/month) makes it an easy first upsell app for a small store to try before paying anything. Try ReConvert.
Pros: visual funnel builder gives more control than a fixed widget, strong app-store rating, usable free tier to start. Cons: more setup time than a plug-and-play widget like Wiser; the deepest personalization features sit behind paid plans.
3. AfterSell — best for one-click upsells right after checkout
AfterSell focuses narrowly on the single highest-converting moment in the funnel: right after a customer enters payment details, before the order confirms. Its AI picks the offer based on what's in the order, and accepting it adds the item to the existing order with one click — no new checkout, no re-entering a card. That narrow focus is the trade-off: AfterSell doesn't try to cover product-page or cart cross-sells the way Wiser or Selleasy do. Try AfterSell.
Pros: highest-converting upsell placement in the funnel, genuinely one-click for the customer, AI-selected offers rather than static ones. Cons: starts pricier than the other options here, no permanent free plan beyond the trial, and it's a single-stage tool rather than a full-funnel one.
4. Selleasy — best free option overall
Selleasy covers product-page, cart, and thank-you-page cross-sells and bundles in one app, and its free plan (up to 50 orders/month) is genuinely usable rather than a crippled trial — a meaningful share of its App Store reviews come from small stores that never needed to upgrade. For a seller who wants to test whether AI cross-sells move the needle at all before spending anything, this is the lowest-risk place to start. Try Selleasy.
Pros: free tier that actually works at real order volume, covers product page through post-purchase in one app, straightforward setup on any theme. Cons: less deep personalization than a dedicated post-purchase specialist like ReConvert or AfterSell once you're past the free tier's order cap.
5. Bold Upsell — best for cross-sell widgets across the whole funnel
Bold's AI Upsell & Cross-Sell app spreads its widgets across product, cart, and checkout pages (checkout requires Shopify Plus), so a shopper sees a relevant offer at whichever stage they're actually at rather than just one fixed spot. Bold is one of the older, more established names in this category, and that maturity shows in theme compatibility and support. Try Bold Upsell.
Pros: widgets at multiple funnel stages instead of one, free plan to start, established app with broad theme support. Cons: the free plan is limited, and full checkout-stage upsells need Shopify Plus to unlock.
How to choose
- You're small and don't want to pay for anything yet: Wiser AI or Selleasy — both run free under 50 orders/month and cover the bulk of the product-page and cart cross-sell use case.
- You want to build a specific post-purchase funnel with your own logic: ReConvert's visual editor gives you that control for a low starting price.
- You want the single highest-converting upsell moment and nothing else: AfterSell's one-click, right-after-checkout offer.
- You want one app covering product, cart, and checkout together: Bold Upsell.
The honest verdict: start free. Wiser or Selleasy will tell you within a few weeks whether AI-suggested bundles actually move your average order value, and only once you've confirmed that does it make sense to add a specialist like ReConvert or AfterSell for the post-purchase stage specifically — that's the single highest-converting placement, but it's an addition to product-page cross-selling, not a replacement for it — if bundling specifically (rather than one-off upsells) is the format you want to lean on, our best AI tools for Shopify product bundling guide covers that narrower category in depth, and if you want the same kind of AI-driven suggestions shown earlier in the browsing journey rather than at the cart or post-purchase stage, our best AI tools for Shopify product recommendations roundup covers that upstream piece. If checkout itself is where you want to focus that spend, our best AI tools for Shopify checkout optimization guide covers the Plus-specific checkout apps in more depth. And once a customer has bought, the upsell doesn't have to stop at the thank-you page — our best AI email marketing tools for ecommerce roundup covers the follow-up cross-sell sequences that run after the order ships, and our best AI tools for Shopify abandoned cart recovery guide covers the flip side — winning back the carts that never converted at all. For general background on why bundling and cross-selling work, Shopify's own guide to cross-selling is a reasonable primer.
Frequently asked questions
What's the difference between an upsell and a cross-sell app?
An upsell offers a better version of what's already in the cart — a bigger size, a pricier bundle, a subscription instead of a one-off. A cross-sell offers something different that pairs with it, like Amazon's 'frequently bought together.' Most of the apps on this list, including Wiser, Selleasy, and Bold Upsell, do both from the same widget rather than making you choose.
Where should I show the upsell — product page, cart, or after checkout?
All three work, and they're not mutually exclusive. A product-page cross-sell (Wiser, Selleasy) catches a shopper while they're still deciding. A cart-page upsell nudges someone who's already committed to buy something. A post-purchase, one-click upsell (ReConvert, AfterSell) works on a customer who has already entered payment details, so accepting it takes one click and no new checkout — in our comparisons that stage consistently converts at the highest rate per offer shown.
Do I need a paid app, or can I do this for free?
If your store does under 50 orders a month, Wiser and Selleasy both run free at that volume, so there's no reason to skip AI upsells while you're small. Once you cross that threshold, pricing scales with order count on most of these apps, so the subscription should still be a small fraction of the extra revenue the upsells generate.
Will adding upsell popups hurt my checkout conversion rate?
Badly timed or irrelevant ones will. The apps that use AI to pick the specific offer from a shopper's actual cart contents — rather than showing the same static popup to everyone — perform better precisely because they only interrupt with something relevant. If you're seeing conversion drop after adding one of these, cut the number of offers per page before you cut the tool.
